Welcome to the Q&A Forum

Hi There, That seems to be a bit strange and to be honest I have not seen that before. In this case I would recommend writing into help@moz.com and attach the CSV that is giving you trouble to the email. We generally prefer to work through emails sent to help@moz.com because you can speak directly with a customer service representative and we can give you updates if we need to speak with our engineering staff. In the meantime if you have any other questions or concerns please feel free to ask and I would be happy to help. Have a great day and I look forward to speaking with you soon.
